GRUNDIG LCD TV-schematic-Berlin, Vision-7 and Vision 9- How to enter the service mode, service mode adjustments method [Full circuit diagram]

 

Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

It makes sense to avoid exposure to electrical shock.  While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

Calling up the Service Mode
– Press button " i " (Menu: PICTURE).
– Enter the code number "8500".
